Protein can help support muscle when paired with resistance exercise, but the right intake depends on body size, health, diet, and activity—not a one-size-fits-all longevity stack.
For many older adults, protein is most useful as part of a muscle-preserving plan that includes resistance exercise—not as a stand-alone anti-aging supplement. A position paper from the PROT-AGE Study Group suggests 1.0–1.2 grams of protein per kilogram of body weight per day for adults over 65, with individual needs affected by activity and health status (PROT-AGE paper). This is guidance, not a personal prescription.
People vary in body size, appetite, activity, kidney health, and medical conditions. Older adults recovering from illness or living with chronic disease may have different requirements. Anyone with kidney disease or a prescribed protein restriction should ask their clinician before increasing intake.
Protein supports tissue repair, but muscle responds to more than food alone. A 2025 meta-analysis of trials in people with sarcopenia or physical frailty found that combined protein and exercise interventions improved some muscle-related outcomes; protein supplementation by itself had more limited effects (systematic review). These findings do not show that protein powders extend lifespan.
Start by reviewing a few typical days of eating. Include a protein source at meals—such as beans, lentils, tofu, eggs, dairy, fish, or meat—then consider whether a convenient supplement would close a real gap. Distributing protein across meals can be practical when large servings are uncomfortable, but there is no need to copy an influencer's exact schedule.
If food intake is low because of appetite, swallowing difficulty, dental problems, medication effects, or illness, address the cause with a clinician or dietitian. A powder can supply protein, but it does not provide the full range of nutrients in a balanced diet.
When food alone does not meet an individualized target, compare labels and serving costs:

Do all adults over 60 need protein powder? No. It is a convenience for people who need help meeting an individualized intake target.
Is more protein always better? No. The right amount depends on health and diet, and high-protein eating may not be appropriate for everyone.
Does protein prevent sarcopenia by itself? No. Adequate nutrition matters, but resistance exercise and overall health care are also important.
